Description

Technical field:

[0001] The invention belongs to a biogas device, in particular to a large-scale biogas fermentation device integrating fermentation and gas storage. Background technique:

[0002] As a renewable energy source, biogas is not only clean, cheap, and hygienic, but also gradually shows its unique advantages in many aspects such as the development of ecological agriculture, environmental protection, and comprehensive utilization, and is highly valued by people. However, the existing biogas installations have the following defects: 1. It is necessary to connect equipment for purification and pressure regulation of the biogas between the biogas digester and the biogas burner, such as desulfurizers, pressure gauges, etc., and many pipeline accessories are required to install these equipment. , It takes up a lot of space, and it is not very convenient to operate, manage and maintain. 2. The pressure of biogas is unstable during use, which brings inconvenience to user...
